Abstract

PURPOSE:To efficiently roast charcoal baked rice crackers having high commercial value and to facilitate adjustment of fire, feed of charcoal, etc., by making a fire bed of rice cracker roasting machine of a specific constitution wherein the back of rice cracker dough is baked with charcoal while inverting a roasting net. CONSTITUTION:In a machine roasting rice cracker with charcoal wherein the surface and the back of dough is baked by taking advantage of downward fire of charcoal while successively inverting a roasting net lacing rice cracker dough, a bottom plate 15 of a fire bed 5 having an open top is fixed in such a way that the vertical position of the plate freely adjustable to control fire of charcoal. Further, since the fire bed 5 is placed on a carrier 34 of a vertical driving device 28 and the fire bed 5 can be dropped by the driving device 28, charcoal is readily stored in the fire bed 5, fired, replenished and taken out.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire bed mechanism for a rice cracker charcoal-burning machine in which rice cracker dough is fired by charcoal, ceramic charcoal or the like.

[0002]

2. Description of the Related Art Recently, most of rice crackers are so-called mechanical grills, in which a rice cracker dough is placed on a conveyor and rotated, and then fired from below using gas or electricity. Rarely, there is a place called “Teiyaki rice cracker” which is displayed and sold at the store while grilling over charcoal.

[0003]

However, although the former device that uses a conveyor to sinter with gas or electricity has high production efficiency, it has the deliciousness and flavor of charcoal fired hand-baked rice crackers. Can't get In addition, it is undeniable that the hand-made rice crackers are recognized as having higher commercial value, even if the products themselves are not compared. On the other hand, the latter hand-baked has all the superior taste, flavor, commercial value, etc., compared to the machine-baked, but there is a problem that mass production is impossible and the cost is high.

An object of the present invention is to provide a fire bed mechanism in a charcoal roaster for a rice cracker, which solves the above problems of the conventional art.

[0005]

In order to achieve the above object, a fire bed mechanism in a charcoal-burning machine for rice crackers according to the present invention comprises a charcoal fire with the dorsal and obverse sides of the charcoal fire downward while sequentially reversing the grill net on which the rice cracker dough is placed. In a charcoal roaster of rice crackers that is baked using the heating power of the above, a fire plate with an upper opening in which the bottom plate is vertically adjustable with respect to the grill is placed on the bed of the vertical drive device. It is characterized by

[0006]

[Function] When the rice cracker dough is placed on the grill on the start side and the drive source is started, a large number of the grills arranged in parallel are sequentially inverted from the start side by the inversion mechanism, and the rice cracker is The dough is conveyed in a certain direction while turning it over. As a result, the front and back sides of the dough will be baked using the thermal power of the charcoal fire on the lower floor. In addition, the rice cracker dough is pressed by an upper pressing mechanism in the middle of conveyance, and the expansion caused by baking the dough is appropriately suppressed and adjusted to a constant thickness. Each grill is inverted and the dough is placed on the adjacent grill in reverse, and at the same time, it returns to its original horizontal position in preparation for the next inversion.

Since the bottom plate of the fire bed is vertically adjusted with respect to the grill by the vertical position adjusting mechanism, by adjusting the vertical position in this way, the firepower of the charcoal fire to the rice cracker dough can be arbitrarily adjusted. can do. By moving the loading platform up and down by the vertical driving device, the fire bed placed on the loading platform is moved and adjusted to the ascending position or the descending position. Therefore, not only by adjusting the overall position of the fire bed up and down, it is possible not only to adjust the firepower of the charcoal fire to the grill, but also by descending it, accommodating and igniting the charcoal to the fire bed, and supplementing the charcoal, Alternatively, the charcoal can be taken out conveniently.

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, since the grill 2 is turned over and the front and back sides of the rice cracker dough are baked by the charcoal fire below, the conventional method using gas or electricity is used. The production efficiency is comparable to that of an automatic baking machine, and because it is grilled directly by charcoal, the taste, flavor, and commercial value are significantly improved. Further, by adjusting the bottom plate 15 of the fire bed 5 vertically with respect to the grill 2 ..., it is possible to easily adjust the heating power of the charcoal fire, maintain a proper amount of baking, and give a good-looking focus. it can. Further, since the entire fire bed 5 is mounted on the vertical drive device 28, by lowering the fire bed 5 by the device 28, it is possible to easily introduce charcoal, ignite and take out ash. Is.
